The name derives from either "Herbling" (herb) due to the sour taste of the unripe grape or "Härtling" because of the hard berry skin. Martin already used the term Luther (1483-1546) at his Bible translation the parable of the barren vineyard, Isaiah chap. 5, verse 1 to 2: Well, I want to sing to my dear friend, a song about my friend and his vineyard.

He also built a tower in it and dug a wine press and waited for it to bring good grapes; but he brought herlings (bad ones) . See also under Irxen (Irxenwein).
